Water Monitoring

GLCA has participated since 1990 in the Citizens Statewide Lake Assessment Program (CSLAP), a volunteer lake monitoring and education program that is managed by NYS Department of Environmental Conservation (DEC) and NYS Federation of Lake Associations. Each year, DEC prepares a summary report for each participating lake association on key indicators of lake water quality (nutrients – primarily phosphorus and nitrogen – plus algae (chlorophyll) and water clarity, as well as other factors impacting lake ecology. Our reports show these positive findings: In the past 30 years, nitrogen and chlorophyll trending lower and, in the past 10 years, surface and deep-water phosphorus have decreased significantly. These trends correlate to GLCA nutrient reduction programs, such as the septic program and the hypolimnetic release of deeper nutrient rich water from the dam’s lower gate.

Keep your septic system in good condition and pump it regularly. Participate in the GLCA pump-out program. Septic problems are significant contributors to nutrient and bacteria levels in the lake. Require boats (including kayaks and paddleboards) and recreational equipment that have been in other waters to be thoroughly cleaned and dried – see boat cleaning. Invasive plants and animals (such as zebra mussels) can migrate from one body of water to another via boats, kayaks, paddleboards and equipment.
